the Fanatical Dwarf Zealot  

dropped the orb last night ill warn you on this guy he is a pally healed himself several times after dropping below 50 pct cast a couple mionor dd's as well roots only last about 1/4 normal time IF they stick at all rest of my ranger dots landed on him hits for around 150 avg

He also drops ores, mining picks and for us he dropped this:

Tattered Hide Tunic
MAGIC ITEM LORE ITEM
Slot: Chest
AC: 16
HP: +30 MANA: +30
SV FIRE: +5 SV DISEASE: +5 SV COLD: +5 SV MAGIC: +5 SV POISON: +5
Recommended level of 42.
WT: 1.5 Size: LARGE
Class: DRU MNK BST
Race: ALL

By the way, he casts spells. He casts direct damage spells, and also heals himself.

He is also significantly more resistant to spells than other miners in the zone. He was difficult to root, broke root quickly, and also resisted my fire-based direct damage spell a bit more I would have expected. He is significantly more difficult than the regular miners.
